There exists an old saying in American culture: “The eyes are a window to the soul.”
Jesus spoke about this when He taught on how our eyes reflect either spiritual light or great spiritual darkness within our souls. “The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light. But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness.” Matthew 6:22&23
Jesus makes certain that there is no misunderstanding that either we are full of light or we are in great darkness. Just as we cannot love two masters, so that there cannot be any neutrality in the state of our souls.
How and what makes the difference between an eye full of light and an eye full of darkness? To know this you have to understand light and know where darkness comes from.
Spiritual darkness came upon all mankind without exception in the Garden of Eden when Adam and Eve rebelled against God. Adam and Eve’s pride drove them to eat of the tree of the knowledge of good and evil. “Because that, when they knew God, they glorified him not as God, neither where thankful; but became vain in their imaginations, and their foolish heart was darkened.” Romans 1:21
Through Adam and Eve’s sin and pride, mankind was thrust into “great” spiritual darkness and sadly, this darkness exists today.
From where comes the light?
Jesus said in John 9 verse 5, “As long as I am in the world, I am the light of the world. “When Jesus went back to heaven He promised He would send another light: God, the Holy Spirit, also known as the Comforter. “But when the Comforter is come, whom I will send unto you from the Father, even the Spirit of truth, which proceedeth from the Father, he shall testify of me.” John 15:26
The Holy Spirit comes to dwell within each person to whom the Father sends Him. His presence within us is the proof we have become one of God’s people. If we are one of the blessed recipients of God’s gift of salvation, the Spirit will remain in us forever.
“And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever.” John 14:16
The Spirit is the light that rekindles the light that was darkened by our sin and the sin of Adam. Through the Spirit’s presence and power each and every person in whom the Spirit dwells become the light of the world:
“Ye are the light of the world. A city that is set on a hill…” that cannot be hid. Matthew 5:14
This is now our purpose and task, if the Spirit of God dwells within us:
“Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.” Matthew 5: 16
